Space syntax analysis applied to urban street lighting: Relations between spatial properties and lighting levels
2019
According to the international technical standards, higher lighting levels (luminance and illuminance levels) are expected in trafficked and central roads (where restrictive minimum lighting requirements are necessary) and lower lighting levels are expected in peripheral and less trafficked roads. Starting from this assumption, in this paper, the authors analyse the correlations between spatial properties (expressed by spatial indicators, for example, the integration index and the choice index) and lighting levels (expressed by lighting parameters, for example luminance and illuminance) upon roads of an urban context. The analysis has been applied to the case study of the medium sized town …
A new index for measuring seasonality: A transportation cost approach
2017
Abstract Seasonal fluctuations characterize many natural and social phenomena. Although the causes and impacts of seasonality are generally well documented in different study contexts, and many methods for isolating the seasonal component have been developed, considerably less attention has been paid to the measurement of the degree of seasonality. After reviewing the main indices used for measuring seasonality in different study contexts, we will propose a new approach in which seasonality is evaluated on the basis of the solution of a transportation problem. By considering the interdisciplinary nature of seasonal phenomena, the topic of measuring seasonality merits attention from a wide v…
Sequential injection analysis (SIA)-chemiluminescence determination of indomethacin using tris[(2,2'-bipyridyl)]ruthenium(III) as reagent and its app…
2006
Abstract Automated sequential injection (SIA) method for chemiluminescence (CL) determination of nonsteroidal anti-inflammatory drug indomethacin ( I ) was devised. The CL radiation was emitted in the reaction of I (dissolved in aqueous 50% v/v ethanol) with intermediate reagent tris(2,2′-bipyridyl)ruthenium(III) (Ru(bipy) 3 3+ ) in the presence of acetate. The Ru(bipy) 3 3+ was generated on-line in the SIA system by the oxidation of 0.5 mM tris(2,2′-bipyridyl)ruthenium(II) (Ru(bipy) 3 2+ ) with Ce(IV) ammonium sulphate in diluted sulphuric acid. The optimum sequence, concentrations, and aspirated volumes of reactant zones were: 15 mM Ce(IV) in 50 mM sulphuric acid 41 μL, 0.5 mM Ru(bipy) 3 …
Applying system dynamics to foster organizational change, accountability and performance in the public sector: A case-based Italian perspective
2010
The goal of this paper is to discuss the role System Dynamics (SD) can play to enhance performance improvement in the public sector. It is remarked how SD can help decision makers to properly perceive the boundaries of the relevant system underlying observed phenomena. To this end, three real cases are analysed to show how SD can facilitate a better understanding of the relationships between the political and the organisational system in the public sector, and how to promptly attain efficiency and improve outcome, given the constraints that the institutional and political systems constitute. The goal of this paper is to discuss the role System Dynamics (SD) can play to enhance performance i…
The real-life performance of market timing with moving average and time-series momentum rules
2014
In this article, we revisit the myths regarding the superior performance of market timing strategies based on moving average and time-series momentum rules. These active timing strategies are very appealing to investors because of their extraordinary simplicity and because they promise substantial advantages over their passive counterparts. However, the ‘too good to be true’ reported performance of these market timing rules raises a legitimate concern as to whether this performance is realistic and whether investors can expect that future performance will be the same as the documented historical performance. We argue that the reported performance of market timing strategies usually contains…
A framework for a network-level performance measurement system in SME networks
2008
The present study aims to present a theoretical framework for a network-level performance measurement system. The suggested framework for the performance measurement system is composed of the factors that enable and cause the productivity and profitability of the network form of organisation. The framework developed in this study can be divided into six subdimensions: (1) network culture, (2) resources and competences, (3) models of action, (4) internal processes, (5) customer perspective and (6) financial indicators of the network. We argue that this framework provides research opportunities to study the performance of the network form of organisation; but even more importantly, it provide…
Conflicting interests but filtered key targets: Stakeholder and resource-dependency analyses at a University of Applied Sciences
2013
Stakeholder theory (SHT) emphasizes that different stakeholders and their interests need to be identified and addressed to maximize firm performance. This emphasis can make the design of performance measurement systems (PMS) challenging because the interests of stakeholders are often in conflict. Based on previous research and using stakeholder and resource dependency theories, we develop a theoretical model suggesting that resource dependency acts as a “filter” in selecting which of the PMS design measures are emphasized for decision making. We find various conflicting interests between stakeholders in our case organization (a unit of University of Applied Sciences in Finland) that affecte…
